Well, to understand why and how, first you have to ask yourself why and how they allow hundreds of millions of users access to the application and all its computing power for FREE? We take the approach that nothing is free and there has to be fine print. So we did the digging and this is a direct quote from the user policy on a global chat app company.
“In order to operate and provide our Services, you grant Whatsapp a worldwide, non-exclusive, royalty-free, sublicensable, and transferable license to use, reproduce, distribute, create derivative works of, display, and perform the information (including the content) that you upload, submit, store, send, or receive on or through our Services. The rights you grant in this license are for the limited purpose of operating and providing our Services”
All the FREE chat apps have something similar, and it is only understandable if you can disseminate the lengthy user and privacy policies of these lawyer written terms. So if your understanding is similar to ours, with the idea that nothing is FREE than you must now understand why we built Hola. Check out our blog for more outsourced written articles on the subject.
